Answer:
Part A.
w = √(d^2 - l^2)
Part B.
w = 6ft
Step-by-step explanation:
length l = 8ft
diagonal d = 10ft
width w = ?
we can see it as a Trangle, so using a Pythagorean theorem,
d^2 = l^2 + w^2
w = √ (d^2 - l^2)
w = √ (10^2 - 8^2)
w = √ (100 - 64)
w = √ 36
w = 6
Answer:
y
Step-by-step explanation:
Answer:
x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5(2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = -72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2(12) - 15
x = 24 - 15
x = 9
Hello!
Answer:
The amount is-
Cupcakes-12
